MANUFACTURE OF "WIREROPE.

Specification of Letters Patent.

Patented May 25, 1920.

Application filed. May 4, 1920. Serial No. 378,831.

To all whom it may concern: 7

Be. it known that I, Gnonen PYBURN, of Caledonia House, Cairnhill Road, Airdrie, Scotland, foreman wire-rope maker, have invented certain new and useful Improve- Inents Relating to the Manufacture of Wire Hopes, of which the following is a specification.

liy invention which relates to the manufacture of wire-ropes has for its object to provide an appliance of a more simple and effective nature than at present in existence for obviating the necessity of all winding of wire from the hank as manufactured by wire-drawer on to bobbins, than placing these in the stranding machine, and it also obviates the necessity of winding the wire by using a collapsible reel on the machine, all hereafter described with reference'to he drawings and pointed out in' the claim.

In order that my invention maybe properly understood and readily carried into effect, I have hereunto appended one sheet of drawings, of which- Figure 1 is a view looking on theunderside of reel.

Fig. 2 is an elevation.

3 is a plan looking on toppt reel.

Fig. at is a section in line X. X. *ig. 3.

In carrying out my invention, I provide a plate A of any suitable metal or material having distance pieces 0 fixed thereto at equal distances apart, the ends of which pass through holes or openings in the plate A and have each a spring S bearing on the face Roi the distance pieces 0 on the underside of the plate A. so

Carried on each distance piece 0 there is a spiral spring T which bears upon and has a tendency to press down catch P on the coil or wire which lies between the plate A and catch P thereby retaining the wire in the coil as it was wound when being manufactured.

,ll hen placing the wire hank in position the catches P are turned out of the way by twisting or turning the distance pieces and which are held in that position by the springs S bearin against the plates R of the distance pieces F) on the under-side of the base plate A. After the hank has been placed in position on the collapsible reel the catches P are again turned back when the springs T automatically press the catches on to the hank of wire.

nuts M. Pivotedat E toeach of the pins Y or bars E there a collapsible adjustable arm D of trough-shaped formation. Carried on a cross-bar or pin G fixed to or forming part of each of the collapsible arms D there is a link G, the other end of which being pivoted between two snugs H fixed to or forming part of a loose sleeve C carried on the boss B Under the sleeve and also carried on the boss 13 there is a spiral spring L which causes the collapsible arms D to automatically return to their normal position. A collar B is also provided at upper end of boss B to limit the movement of the sleeve C. There is also an adjustable screw J for tightening up the sleeve C after adjusting the arins D. The collapsible reel is always adjusted before the coil or hank is placed thereon'so as to accommodate the hank to be uncoiled. The wire is drawn from the coil between the plate A and catches P by the action of the machine which revolves and twists the wire into strands. As this action proceeds, the coil between the plate A and catch P is reduced in size, and in order that the same may retain its form and thus enable the wire to be drawn oil the catclrl? by means of the springs T press on the wire and thereby keep it firm and this prevents looseness in the hank of wire. The adjustment of. the arms D to enable the coil to be placed in position is eil'ectedby loosening the screw which enables the collar or sleeve C to be moved up or down on the boss 1 The upper ends of the adjusting arms are thus pulled inward the desired distance and in so doing the collar G moves down the boss 13 taking withit the inner ends of the links G when they are fixed in that position by the tightening screw J. llhe'n the collar or sleeve C is again released by the screw J, the sleeve 0, by the action of the coiled spring L rises admitting of the adjusting arms returning to their normal position. The circumference of the collapsible bobbin or reel is, adjusted by the nut M carried on the threaded part of the pin or bars E being loosened and the pins or bars E carrying the tightening bars D being moved outward or inward, as desired. The coil of wire is placed on the collapsible reel above referred to to hold it firmly and retain it in position in the machine whereby there will be no trouble of any fankled hanks or looseness at the finish of the hank.

A suitable friction brake V is placed on the underside of the plate A.

. Claim.

A reel of the class described comprising a plate having a central opening, a tubular boss on one side concentric with said opening, said plate having radial slots; distance pieces pivotally mounted on said plate, arranged equidistant from the center thereof and having angular faces at the pivotally mounted end, catches slidably mounted on sleeve outwardly.

the distance pieces,'springs to move said catches toward said plate, springs to engage the said angular faces and hold said distance pieces and catches against casual turned to said sleeve and to said arms, and a spring on said tubular boss to move said In testimonywhereof I aflix'my signature in presence of two witnesses.
